www/apache-tomcat9: Update to 9.0.38

Changes for 9.0.38:
  - For requests containing the Expect: 100-continue header, optional
    support has been added to delay sending an intermediate 100 status
    response until the servlet reads the request body, allowing the
    servlet the opportunity to respond without asking for the request
    body. Based on a pull request by malaysf.

  - Add support for a read idle timeout and a write idle timeout to the
    WebSocket session via custom properties in the user properties
    instance associated with the session. Based on a pull request by
    sakshamverma.

  - Update the packaged version of the Tomcat Native Library to 1.2.25

Changes for 9.0.37:
  - Implement a significant portion of the TLS environment variables for
    the rewrite valve.
  - Improvements to the creation of OSGi manifests.
  - Reduce the memory footprint of closed HTTP/2 streams
  - Improve parsing of RFC 2109 cookies

Changes for 9.0.36:
  - Add support for ALPN on recent OpenJDK 8 releases.
  - Add support for the CATALINA_OUT_CMD environment variable that
    defines a command to which captured stdout and stderr will be
    redirected. For use with, for example, rotatelogs. Patch provided by
    Harald Dunkel.
  - Be more flexible with respect to the ordering of groups, roles and
    users in the tomcat-users.xml file

Changes for 9.0.35:
  - Improve the handling of requests that use an expectation. Do not
    disable keep-alive where the response has a non-2xx status code but
    the request body has been fully read.
  - Change default value separator for property replacement to ":-" due
    to possible conflicts. The syntax is now "${name:-default}".
  - Update the packaged version of the Tomcat Native Library to 1.2.24.
